The rain pattered against the window, casting shadows long and dark upon the crumbling mansion’s walls. A single candle flickered weakly, casting eerie light that danced across the dusty floorboards. The clock struck midnight with a loud, jarring chime, signaling the end of another tense, uneasy evening. A shadowy figure slipped past the curtains, their breath visible in the cold, damp air. Whispers echoed faintly through the empty halls, though no one dared to turn and see who spoke. The butler stood rigid, his knuckles white around the brass candlestick, watching the room with hollow eyes. Each step felt heavier than the last, as if the house itself seemed to drag them deeper into its sinister embrace. The last light died out, plunging the grand foyer into complete, suffocating darkness. A key turned in the lock with a sound like a knife slicing through silence. The door swung open, revealing a figure wrapped in a coat that seemed too large for them. Their breath came in ragged gasps, their face pale beneath the dim glow of a single lantern. The air smelled of old wood and something far more sinister, something that clung to the walls like a curse. A voice, soft yet commanding, called out from the darkness, breaking the tense, suffocating spell. The figure hesitated, then stepped forward, their footsteps echoing ominously down the hall. The lantern flickered once, twice, before plunging them into darkness once more. A gunshot rang out, sharp and final, echoing through the empty house. The figure collapsed to the floor, their body still warm, their eyes wide with terror.
